The supply of hydrogen ions will also depend upon their concentration, i.e. the pH of the electrolyte. A concentration gradient in the electrolyte is illustrated. ·If the electrolyte is unstirred, the ...

If the hydrogen ion concentration increases by a factor of 100 (10 2), the pH decreases by 2. A solution of 0.8 mol/dm 3 hydrochloric acid has a pH of 0.1. Predict its pH when it is diluted to 0. ...
